Using Coke's words, "a surrender properly is a yielding up of an estate for life or years to him that hath an immediate estate in reversion or remainder wherein the estate for life or years may drown by mutual agreement between them": Co. Litt. 337 b. It seems to me that it really begs the question to say that after the notice to quit Virgona had no estate or interest in the land. He had in the ordinary sense no proprietary right, because he could not assign his right to remain in occupation. He had of course no estate in the feudal sense. What we now call a tenancy was not a tenure. Not until the end of the fifteenth century could it be said that a termor had an estate in land. Thereafter it could be, because the action of ejectment secured the tenant in his possession. What rights did the law actually give to Virgona? That, rather than their description, is the essential question. It gave him a right to continue in occupation subject to his performing in favour of his landlord the taxpayer what had formerly been his contractual obligations under the lease, to pay rent and so forth. Until he should be ordered by a competent court to give up possession, he had a right to exclusive possession as against all others including his landlord. Such a right, when it flows from contract with the landlord, is the very essence of tenancy. It creates an interest in land: Radaich v. Smith [1] . It seems to me that this same right when it flows from statute rather than from contract is an interest in relation to the land, if not, in a technical sense, an estate in the land. It is true that this statutory tenancy does not fit into the earlier known categories. It is a new creation. Its incidents are its own. It is true that the statutory tenant cannot assign his right of occupation. It is a personal right although in some cases it descends upon his death. Doubtless a right to assign the term to a stranger is an incident of an ordinary leasehold, although it may be restricted by the provisions of the lease. But this seems to me to be of itself inconclusive. I see no reason why the word "surrender" should not be thought appropriate to describe an abandonment in favour of his landlord of a statutory tenant's rights to possession. The landlord recovers his estate unrestricted by them. Dixon C.J. observed in Arnold v. Mann [1] that in the field of statutory tenancies the use of terms cannot be given its former significance. We must, it seems to me, look at the nature of the rights and see whether they cannot be said to be surrendered. Fullagar J. found no difficulty in Andrews v. Hogan [2] , in this use of the word in the Act there under consideration. And I find no difficulty here. Some parts of the language of the Income Tax and Social Services Contribution Assessment Act might have surprised Sir Edward Coke. For example, the opening words of s. 88, "a premium in respect of land, premises or machinery", when referred back to the definition in s. 83 show that a premium for the surrender of a lease includes a price paid for putting an end to a lease of machinery. The rights of a lessee under a lease of machinery are not I would think ordinarily an assignable proprietary interest in the machinery. A lease of machinery is not a demise. It is a hiring. The proprietary interest remains in the owner. The hirer gains a legal right of possession and during the period of the hiring the true owner is debarred from resuming possession against the hirer's will. The word "reversion" seems to me inapt to describe the ownership of chattels let on hire.
